I bought several rings recently at an auction, and from afar I thought they were all glass. When I got them home and took a look at this ring, I immediately knew is was very special. I took it to a jeweler who confirmed it was a high quality huge faceted quartz stone in a sterling setting. The color looks different in different lights, but it is from a pale yellow to a light brown and a deeper brown. The stone is just over 3/4 inch long and just over 1/2 inch wide. It is also about 1/2 inch deep. It is faceted on all sides in quite an unusual manner that makes the ring pop and sparkle like a huge gemstone. It is a ring size 7 and in excellent condition. This ring truly makes an elegant statement and quite comfortable to wear too.
